<strong>Extracting</strong> <strong>data</strong> <strong>from</strong> <strong>the</strong> <strong>Synergetic</strong> <strong>data</strong>base<br />
Advanced Microsoft Query and SQL examples<br />
Example 1 - Use SUBSTRING with a character string<br />
This example shows how to return only a portion of a character string.<br />
From <strong>the</strong> vStudentClasses view, this query returns records filtered based on a portion of <strong>the</strong> class<br />
code.<br />
Query<br />
SELECT<br />
vSC.StudentID, vSC.StudentSurname, vSC.StudentPreferred,<br />
vSC.StudentCampus, vSC.StudentHouse, vSC.ClassCampus, vSC.ClassCode,<br />
vSC.ClassDescription<br />
FROM vStudentClasses vSC<br />
WHERE (substring(vSC.ClassCode,1,2)='MA')<br />
ORDER BY<br />
vSC.StudentSurname,<br />
vSC.StudentPreferred<br />
The WHERE substring statement selects MA because <strong>the</strong>re is a character match starting <strong>from</strong><br />
position one which includes two characters of <strong>the</strong> class code.<br />
